Abstract

The paper analyzes the influence of the impact rate of up to 120 ms-1 with a constant energy on the relative compression of high-grade unalloyed steels, Cu and Zn, and the evaluation of energy consumed during the impact bending test at the impact rate of up to 80 ms-1. Based on the experiments made, relationships for the prediction of the influence of the strain rate within the range of 10-3 – 2.5.103 s-1 on the mechanical properties of high-grade unalloyed steels with the yield point of 210 – 450 MPa and microalloyed steels with the yield point of 300 – 600 MPa are presented.
